Docker bash提示不显示颜色 [英] Docker bash prompt not display color

问题描述

我使用命令： docker运行--rm -it govim bash -l <​​/ code>运行docker映像，但
它不能显示bash提示颜色。如果我 source〜/ .bash_profile 或再次运行 bash -l <​​/ code>，bash提示显示颜色正常。

解决方案

由于 chepner 已评论（较早的回答），。 bash_profile 来源（它是一个交互式shell），因为 bash_prompt 是由 .bash_profile 调用。

但 docker issue 9299 说明 TERM doesn' Ť似乎立即设置，强制用户打开另一个bash：

  docker exec -ti test env TERM = xterm bash -l 
  

与 issue 8755 。

To 说明/重现问题：

  docker exec -ti $ CONTAINER_NAME tty 
不是tty 
  

目前的解决方法是：

  docker exec -ti`your_container_id`脚本-q -c/ bin / bash/ dev / null 
  / pre> 
 
 
两个都假设你先运行一个运行容器，这可能不方便。
 
 
 
 
 
 
 T他 OP SolomonT 报告说  docker run   with   env  做工作：
  docker run -rm -it -eTERM = xterm-256colorgovim bash -l 
  
 
 
 
 
 
 
而 Fernando Correia 添加了在评论：
 
 
为了获得颜色支持并使tmux工作，我结合了两个例子：
 
 
 
 
 
  docker exec -it my-container env TERM = xterm脚本-q -c/ bin / bash/ dev / null 
  
 
I use command: docker run --rm -it govim bash -l to run docker images but 
it cannot display bash prompt color. If I source ~/.bash_profile or run bash -l again, bash prompt display color like normal.

解决方案
As chepner commented (earlier answer), .bash_profile is sourced (itis an interactive shell), since bash_prompt is called by .bash_profile.

But docker issue 9299 illustrates that TERM doesn't seem to be set right away, forcing the users to open another bash with:
docker exec -ti test env TERM=xterm bash -l
You have similar color issues with issue 8755.

To illustrate/reproduce the problem:
docker exec -ti $CONTAINER_NAME tty
not a tty
The current workaround is :
docker exec -ti `your_container_id` script -q -c "/bin/bash" /dev/null
Both are supposing you have a running container first, which might not be convenient here.



The OP SolomonT reports that docker run with env do work:
docker run --rm -it -e "TERM=xterm-256color" govim bash -l




And Fernando Correia adds in the comments:

  
To get both color support and make tmux work, I combined both examples: 


docker exec -it my-container env TERM=xterm script -q -c "/bin/bash" /dev/null
